The Best Foods to Eat If You Have High Blood Pressure

The number of Americans dealing with high blood pressure is inching closer and closer to half of the adult population, making it more important than ever to explore new ways to lessen the negative impacts of hypertension. While foods with higher sodium levels are dangerous to blood pressure levels, there are plenty of foods that can have the opposite effect. To find out more about how some of these foods can help fight against hypertension, Cheapism talked to Megan Wong, a registered dietitian at the dietary-supplement company AlgaeCal, and Lisa R. Young, Ph.D., a registered dietitian and adjunct professor of nutrition at New York University.

Legumes such as kidney beans are high in potassium, which is what makes them useful when it comes to lowering blood pressure — potassium helps the kidneys eliminate excess sodium, balancing out the negative effects of high sodium intake. According to Wong, kidney beans in particular should be part of your diet if you struggle with hypertension — Wong says that three-quarters of a cup of kidney beans contains about 537 milligrams of potassium, which is more than a large banana.

Dairy products are full of essential minerals (especially calcium and magnesium) that can help regulate blood pressure, so that alone makes yogurt a contender for this round-up. But what cements yogurt as a go-to choice for people struggling with hypertension is the beneficial bacteria it contains — the bacteria causes the release of proteins that can lower blood pressure. In a recent study, researchers discovered that there is a direct link between eating yogurt daily and lower overall blood pressure, especially for people with pre-existing hypertension issues.

Since berries are an excellent source of antioxidants, they are chock full of benefits that make them ideal for lowering blood pressure, according to Young.

Omega-3 fatty acids are notorious for a slew of health benefits, many of which are tied to heart health and reducing inflammation.

Opt for spinach, kale, arugula, or spring mix instead of iceberg lettuce next time you make yourself a salad, and don’t stop there. You can sneak spinach into your morning smoothie, add it to a sandwich, or mix it in with scrambled eggs. However you incorporate it into your diet, spinach is a must-have if you’re trying to lower your blood pressure. The superfood is a good source of potassium, fiber, and the antioxidant lutein — all things that can relax blood vessels and lower blood pressure. Spinach is also magnesium-rich, which has been known to lower blood pressure.

Wong also suggests beets to lower blood pressure, explaining that they are rich in inorganic nitrate, which converts to nitric oxide. As a vasodilator, nitric oxide widens and relaxes blood vessels, which lowers blood pressure and simultaneously improves blood flow. Celery is another food that offers the same benefits — not to mention it’s largely void of calories.

As the quintessential superfood, it’s no surprise that sweet potatoes are good for hypertension — after all, what aren’t they good for? While the salt content and calories of regular potatoes rise when they are fried, the same does not happen with sweet potatoes, so you can enjoy sweet potato fries guilt-free. Like many of the other foods on this list, sweet potatoes are a good source of both potassium and magnesium and as an added bonus, they are high in fiber, which decreases the risk of heart problems.

As you carve jack o’ lanterns this year, don’t forget to save the pumpkin seeds for roasting.

These brown and furry on the outside, lush and green on the inside fruits offer quite a bit of nutritional value. Because they are rich in lutein — the same antioxidant found in leafy greens, they are ideal for battling hypertension. A small study also revealed that people who ate three kiwi fruits each day experienced lower blood pressure, and while eating 21 kiwi fruits each week might be a bit excessive or unrealistic, it’s certainly not a bad idea to incorporate them into your diet.

You don’t have to swear off dessert in order to lower your blood pressure. On the contrary, dark chocolate is rich in magnesium, which as you’ve figured out by now, helps relax and widen blood vessels.
